The Queen of Light, which was hit by a ray of dark energy, returns to her original shape, divided into three parts: the life, the heart (i.e the throne of the Queen) and the twelve Hearts of Magic, which represent her aspirations.

So, Nagisa and Honoka become the legendary warriors, Pretty Cure again to find all the pieces of the Queen and prevent the Evil King from awakening. They are then joined by Kujou Hikari, who transforms into Shiny Luminous, who is the very life of the Queen of Light.
